Is there a way to quickly convert radians to degrees and back in windows calculator without using the formula:

radians = degrees * Math.PI/180

(something similar to converting between number base by just clicking on DEC/HEX radio buttons).

Just put it into google, and google can convert it for you. Google calculator works from the search prompt, and can convert pretty much any unit to any other unit.

Try a "search" for:

3.7 radians in degrees

or

107.8 degrees in radians

It can do an awful lot more too.

How does this even remotely relate to the question? – Rook Sep 2 '10 at 1:09

It's a way to convert degrees to radians without any special software. – JNK Sep 2 '10 at 1:50
A calc isn't that "special", methinks. The man asked how to do it in calc; you answer "google". Therefore my question. Nwm. – Rook Sep 3 '10 at 2:26
Well instead of saying "no" with no further info, I offered an alternative. That's the spirit of this site, offering assistance. – JNK Sep 3 '10 at 2:31

To convert degrees to radians, copy the following text *p/180= then in Calculator you can press Ctrl+V to convert. For example,

45 Ctrl+V 0.78539816339744830961566084581988
90 Ctrl+V 1.5707963267948966192313216916398
180 Ctrl+V 3.1415926535897932384626433832795
360 Ctrl+V 6.283185307179586476925286766559

To convert radians to degrees, copy the following text *180/p= then in Calculator you can press Ctrl+V to convert. For example,

1 Ctrl+V 57.295779513082320876798154814105
2 Ctrl+V 114.59155902616464175359630962821
3.14 Ctrl+V 179.90874767107848755314620611629

Be aware that when you copy something, the conversion function will be lost. With that in mind, these pasteable conversion functions might be useful if you have several conversions to make, but might be less useful for multi-step calcuations that you want to copy and paste results from.

Not without doing the multiplication yourself (you could store the factor in the memory).

You may like Calc98. Using it, you:

  • press the Unit button
  • select angle in the Property field
  • select deg in the From field
  • select radians in the to field
  • click OK
  • enter a number and click the cnv> button, repeat this step for additional conversions
